Honestly, I am not sure. The performance under Mavericks has been so bad I just haven't been motivated to use the software lately. My misfunctioning auto save feature that wasn't saving my work causing a huge loss of work on a project has just left me frustrated.

Both. I tried opening and rendering a template which was painfully slow. Put the project onto a flash drive and did it in about 1/4 the time in a non-Maverick Mac. My Mac: 3.06 Ghz intel Core 2, 4gb 1067Mhz DDR3 memory running OS10.9

I honestly feel like it has ruined my computer. It was functioning perfectly, no complaints, prior to the update. And now it sucks. Planned obsolescence on Apples part? Make an "upgrade" that isn't easily undone and cripples older systems.
